Celebrating sleep
World Sleep Day, observed on 21 March, was created to bring attention to the growing number of sleep problems worldwide. Sleep is a natural part of human life, but many people in the modern world ignore its importance. As a result, sleep problems are increasingly common.
In 2002, scientists at the University of Athens in Greece conducted a survey of over 35,000 people in 10 countries around the world, including China, Belgium and South Africa. Of the people that responded to the survey, 24 percent said that they did not sleep well, and based on their responses, 31.6 percent were diagnosed (诊断)with insomnia(失眠)and another 17.5 percent were diagnosed with borderline insomnia. In addition, 30.7 percent of survey respondents reported visiting a doctor for help with sleep problems and 11.6 percent said that they felt very sleepy during the day.
Overall, the survey found that ninny people suffer the effects of poor quality sleep, some examples of which are being unable to fall asleep and waking up in the middle of the night. The main factors causing these problems are pressure from school or work and a fast pace of life, but noise pollution and light pollution also interfere with sleep and contribute to poor quality sleep. The survey’s findings are particularly troubling because large numbers of people were found to have difficulty sleeping at night. The short-term effects of this are tiredness and trouble concentrating. If this happens for a long time, the risk of putting on weight and having a heart attack may increase.
There are many things you can do to improve the quality of your sleep. First, you should have regular sleep habits. Try to go to bed and wake up around the same time each day. You also need to make your bedroom a cool, dark, quiet place to sleep so that heat, light and noise do not disturb you. At night, you should also avoid things that contain caffeine, such as chocolate, coffee, tea and many soft drinks, as caffeine may keep you from sleeping.
Getting a good night's sleep is important for everyone. By following the advice above, you can rest better at night and work better during the day.

Some people seem to pick up new vocabularies, master rules of grammar, and learn to write in the new language more quickly than others. Perhaps if we take a close look at these successful language learners, we may discover a few of the techniques which make language learning easier for them.
First of all, successful language learners are independent learners. They do not depend on the book or the teacher; they discover their own way to learn the language. Instead of waiting for the teacher to explain, they try to find the patterns and the rules for themselves. They are good guessers who look for clues and form their own conclusions. When they guess wrong, they guess again. They try to learn from their mistakes.
Success language learning is active learning. Therefore, successful learners do not wait for a chance to use the language; they look for such a chance. They find people who speak the language and they ask these people to correct them when they make a mistake. They will try anything to communicate.
They are not afraid to repeat what they hear or to say strange things; they are willing to make mistakes and try again. When communication is difficult, they can accept information that is inexact or incomplete. It is more important for them to learn to think in the language than to know the meaning of every word.
Finally, successful language learners are learners with a purpose. They want to learn the language because they are interested in the language and the people who speak it. It is necessary for them to learn the language in order to communicate with these people and to learn from them. They find it easy to practice using the language at regular intervals because they want to learn with it.

Why Blue LED Lights Won the Nobel
The 2014 Nobel Prize in physics went to three scientists who gave lighting a big change by inventing blue LED lights. A big change in lighting efficiency is under way around the world.
Save and green
LEDs use less energy than other forms of lighting. A typical LED bulb(灯泡) can produce around 83 lumens per watt — a measure of how much brightness you can get from a unit of electrical power — much more efficient than other lighting facilities.
LEDs produce light by passing electric current through a semiconductor, while traditional bulbs pass current through a wire. The wasted heat energy is chiefly why traditional bulbs are so much less efficient.
LEDs also last about 30 times longer than traditional bulbs, and many LED bulb products promise up to 25,000 hours of use — more than 17 years if you used one for about four hours a day.
Lighting the world
The lighting transformation is not only in homes. LEDs are also being used for street lights, public holiday and decorative displays, commercial buildings, and other large energy users.
Car lighting is another application where LEDs are making progress. LEDs used to be used only for daytime running lights, but now many new cars have LED headlights for night-time use.
LEDs also hold promise for bringing light to the more than 1.5 billion people around the world without access to electricity, the Royal Swedish Academy of Sciences noted. Indeed, several proposed solutions to energy poverty include the distribution of LED lights, particularly solar-powered ones.
Digital displays
Without blue LEDs, the world wouldn’t have back-lit smart phones, TV and computer LCD screens, blu-ray(蓝光) players, many forms of lighting, and countless other products.
In the electronics industry, LEDs provide back lighting for LCD screens in many smart phones, laptops, and televisions. The LEDs are more energy efficient and allow for very thin displays.
Blu-ray players use blue LED lasers(激光) to read data off a digital optical disc. When these systems switched from using an infrared(红外线) laser to a blue LED laser, it became possible to store five to 10 times as much data.
LEDs are now being explored for their potential uses to transmit(传送) data from the Internet across open space, similar to WiFi. Such a system could transmit a lot more data than WiFi alone. This high bandwidth is possible because LEDs can turn on and off millions of times per second.
The rise of LED lighting came at a time when people were just starting to be concerned about global warming. Because of LEDs’ energy efficiency, using them for the world’s lighting would affect environmental protection in a positive way.
Why Blue LED Lights Won the Nobel
The reason why blue LED lights won the 2014 Nobel Prize in physics is that they are to 1.______ in big changes in lighting. | |
Save and green | 2._______ with other forms of lighting, LEDs are much more efficient because of the different ways they pass electric current. What’s more, LED bulbs can be 3._______ 30 times longer than traditional bulbs. |
Lighting the world | 4._______ from household applications of LED bulbs, they can also be used as street lights and car headlights. |
Because of their high efficiency, LEDs, especially solar-powered ones, 5._______ to light areas without access to electricity. | |
Digital displays | Many smart phones, laptops and televisions use LEDs to back-light their LCD6._______. |
By using blue LED lasers, blu-ray players are likely to store 7.________ data. | |
People are now exploring more 8._______ uses of LEDs such as transmitting data. | |
9._______ | LED lighting will have a positive 10.________ on environmental protection. |

Time, a faithful company of our life, is a universal topic. People are always curious about what it is, how it travels and who it meets.
Stephen Hawking, one of the world’s smartest physicists, once said. “I’m fascinated by time.”
Many of us are, and the popularity of time travel novels, movies and TV series has proved that. After Palace and Startling by Each Step achieved astonishing ratings last year, Palace 2 aired on January 20, attracting time travel fans back to TV.
Woody Allen’s movie Midnight in Paris achieved great success. It was nominated for Best Picture, Directing, Original Screenplay and Art Direction for the 2012 Academy Awards.
Dream of heroism
Time travel TV series and movies connect both today and the past, thus offering room for imagination. Imagination creates a chance for the young to fulfill a dream that is hard to achieve in reality.
Chinese writer Xi Juan is a pioneer of time-travel stories in China. In 1993 she published a love story about a young woman time traveling to ancient times. The leading role’s modern personality and perception of love help her win the heart of a cool, handsome martial art master. Such a plot satisfies female fans’ love fantasy.
Starting from the late 1990s, novels about men traveling back to the past prevailed (盛行), with a Step into the Past as the most popular example. In these stories, the male leading roles accomplish great things with their modern skills and wisdom.
It is usually “a dream of heroism come true”, along with enviable romances.
Eye candy
“I’m hooked by the shows because they are characterized by dramatic and poetic love and have eye-pleasing actors,” Xia Xiaoyan, who works for a foreign-owned enterprise in Shanghai, explained her love for time travel TV series.
Her comment echoes a 2011 survey by Creat Marketing Research Co Ltd in China. When asked about what is so appealing about time travel TV series, 21 percent of respondents answered, “These attractive characters.”
A bigger reason behind the popularity of time travel stories, however, is the relaxation they offer, according to the survey.
Cai Yinong agrees. “Many people are facing tremendous pressure in their fast-paced lives, so this genre is more relaxing than other shows as it provides people with a terrific outlet to escape reality,” Cai told China Daily.
Cultural homesickness
“Which dynasty would you like to live in if you could travel to the past?” asked a survey launched by Shanghai University and Shanghai Social Sciences Association last December.
About 60 percent of the 2,543 respondents chose Tang Dynasty, while Qing Dynasty, and the Spring and Autumn and Warring States periods were the other top two destinations.
The survey results reflects people’s definition of the good days: prosperous economy and culture, steady society, fair and uncorrupted politics, and opening up to the outside world.
As for the movie Midnight in Paris, it features modernity versus cultural homesickness. The New York Times commented, “The past seems so much more vivid, more substantial, than the present. The good old days are so attractive because we were not around, however much we wish we were.”

In a society, such as the United States or Canada, which has many national, religious and cultural differences, people highly value individualism-the difference among people. Teachers place a lot of importance on the qualities that make each student special. The educational systems in these countries show these values. Students don't memorize information. Instead, they work individually and find answers themselves. There is often discussion in the classroom. At an early age, students learn to form their own ideas and opinions.
In most Asian societies, by contrast, people have the same language, history, and culture. Perhaps for this reason, the educational system in much of the Orient reflects society’s belief in group goals and purposes rather than individualism. Children in China, Japan, and Korea often work together and help one another in assignments. In the classroom, the teaching methods are often very formal. The teacher lectures, and the students listen. There is not much discussion. Instead, the students recite rules of information that they have memorized.
There are advantages and disadvantages to both of these systems of education. For example, one advantage to the system in Japan is that there much more math and science than American students learn by the end of high school. They also study more hours each day and more days each year than North Americans do. The system is difficult, but it prepares students for a society that values discipline and self-control. There is, however, a disadvantage. Memorization is an important learning method in Japanese schools, yet many students say that after an exam, they forget much of the information that they have memorized.
The advantage of the educational system in North American, on the other hand, is that students learn to think for themselves. The system prepares them for a society that values creative ideas. There is, however, a disadvantage. When students graduate from high school, they haven’t memorized as many basic rules and facts as students in other countries have.

A debate is a discussion about a subject on which people have different views. It’s a nice way of gaining a lot of knowledge and views on a topic, or situation that we aren’t either aware of, or haven’t really looked into in detail. It makes you more able to think critically and more confident in speaking. In addition, it helps in appreciating tolerance of others’ opinion and improves your listening skills.
A debate requires one to know how to use words and intelligence to overcome his or her opposing team members. To give great arguments during a debate, first you need to get your facts right. To make what you have in material for a debate contain facts, don’t just depend on the Internet, especially avoid just referring to one website for all your information. You are also required to refer to books, and make sure they’re authors of a high degree, since their materials have reference notes and extensive research projects done on what they are covering.
Second, you should be full of confidence. You need to show that you’re sure of what you’re saying , and point out how flawed their comeback arguments were. The only way to do this is to thoroughly know your material before heading on out to a debate session. Know your statistics, know your history and above all know names, dates and places. Make key notes to refer to. Don’t stammer (口吃), and also don’t level your gaze with your opponent or the rest of them. All this will help you keep confident.
At last, by no means should you lose your calmness, but keep your voice firm and raised enough to sound calm. A good team member should know how to keep his emotions in control as well as keep others under control in his/ her team.

People unhappy with the rich: Poll
There is growing dissatisfaction toward rich people, according to a new online poll.
The poll by the China Youth Daily in collaboration(与…合作) with Sina.com has highlighted the apparent discontent (不满)over the country's widening income gap.
Nearly 8,000 people filled in online questionnaires last week, and when asked to use three words to describe society's rich, the top responses were "extravagant"(奢侈的), "greedy" and "corrupt".
About 57 percent of those polled said that "extravagant" was the best word to describe the rich, followed closely by "greedy".
Ironically, despite their dissatisfaction, 93 percent of those polled wished they could be rich too, and that richer people should be "socially responsible".
Some 33 percent of respondents also praised rich people for being "smart".
Nearly 90 percent of respondents agreed that most people in society, including themselves, were willing to speak up for the poor but were reluctant to take action and actually do something for them.
The survey comes on the heels of a heated debate over comments made by renowned economist Mao Yushi, who said he was "speaking for the rich and working for the poor".
A report released by the Asian Development Bank last Wednesday revealed that China's Gini coefficient - an indicator of the wealth divide - rose from 0.407 in 1993 to 0.473 in 2004.
An earlier CASS report said that the richest 10 percent of Chinese families now own more than 40 percent of all private assets, while the poorest 10 percent share less than 2 percent of the total wealth.
The country's income disparity(悬殊) is close to that of Latin America, the report which came out in January said.

The family sphere (范围) used to be defined by its isolation from the public realm. There was the public male realm (领域) of "rational accomplishment" and cruel competition, and the private female and child-rearing sphere of home, intuition (直觉) and emotion. The private realm was supposed to be isolated from the realities of adult life. For both better and worse, television and other electronic media tend to break down the difference between those two worlds. The membrane around the family sphere is much more permeable (可渗透的). TV takes public events and transforms them into dramas that are played out in the privacy of our living rooms, kitchens and bedrooms.
Parents used to be the channel through which children learned about the outside world. They could decide what to tell their children and when to tell it to them. Since children learn to read in stages, books provide a kind of natural screening process, where adults can decide what to tell and not tell children of different reading abilities. Television destroyed the system that separated adult from child knowledge and separated information into year-by-year slices for children of different ages. Instead, it presents the same information directly to children of all ages, without going through adult filters.
So television presents a real challenge to adults. While a parent can read a newspaper without sharing it with children in the same room, television is accessible to everyone in that space. And unlike books, television doesn't allow us to flip (翻转) through it and see what's coming up. We may think we're giving our children a lesson in science by having them watch the Challenger take off, and then suddenly they learn about death, disaster and adult mistakes.
Books allow adults to discuss privately what to tell or not tell children. This also allows parents to keep adult material secret from children and keep their secret keeping secret. Take that same material and put it on The Today Show and you have 800,000 children hearing the very things the adults are trying to keep from them. "Television takes our kids across the globe before parents give them permission to cross the street."
More importantly, children gradually learn that adults are worried and anxious about being parents. Actually, television has also places families under a lot of stress.

You can relax if remembering everything is not your strong suit. Recent research makes the case that being forgetful can be a strength—in fact, selective memory can even be a sign of stronger intelligence.
Traditional research on memory has focused on the advantages of remembering everything. But looking through years of recent memory data, researchers Paul Frankland and Blake Richards of the University of Toronto found that the neurobiology(神经生物学) of forgetting can be just as important to our decisionmaking as what our minds choose to remember.
“The goal of memory is not the transmission of information through time. Rather, the goal of memory is to help improve decisionmaking. As such, transience(转瞬即逝) is as important as persistence in memory systems,” their study in Neuron states.
Making intelligent decisions does not mean you need to have all the information at hand, it just means you need to hold onto the most valuable information. And that means clearing up space in your memory palace for the most uptodate information on situations. Our brains do this by generating new neurons(神经元) in our hippocampus(海马体), which have the power to overwrite existing memories that are influencing our decisionmaking.
“If you're trying to deal with the situation and your brain is constantly bringing up multiple conflicting memories, that makes it harder for you to make a wise decision,” Richards told Science Daily.
If you want to increase the number of new neurons in your brain's learning region, try exercising. Moderate aerobic exercise like jogging, power walking, and swimming have been found to increase the number of neurons making important connections in our brains.
When we forget the names of certain clients and details about old jobs, our brain is making a choice that these details do not matter. Although too much forgetfulness can be a cause for concern, the occasional lost detail can be a sign of a perfectly healthy memory system. The researchers found that our brains facilitate decisionmaking by stopping us from focusing too much on minor past details. Instead, the brain promotes generalization, helping us remember the most important gist of a conversation.
“One of the things that distinguishes an environment where you're going to want to remember stuff versus an environment where you want to forget stuff is this question of how consistent the environment is and how likely things are to come back into your life,” Richards said.
If you're an analyst who meets with a client weekly, your brain will recognize that this is a client whose name and story you need to remember. If this is someone you may never meet again, your brain will weigh that information accordingly.
These findings show us that total recall can be overrated. Our brains are working smarter when they aim to remember the right stories, not every story.
Title:Being Forgetful Might Actually Mean You're 1.
